| (54) | Error correction of interleaved data blocks |
| (57) An error correction coding method comprises the steps of dividing data into first
blocks with predetermined size, assigning the data to a plurality of channels and
writing into the memory by making the first blocks a unit, performing a coding of
at least two types of error correction codes for the data written into the memory
for each channel in a second block unit constituted by a predetermined number of the
first blocks and adding a check parity to generate a third block, reading the third
block from the memory by adding a different offset for each of the plurality of channels,
and multiplexing read the third block to a data series in a unit of a predetermined
length. |
